Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
An apparatus for forming at least a two color copy from a single color original document, including: a support member arranged to hold the original document thereon; means for adjustably indicating a portion of the original document to be copied in a first color and a portion of the original document to be copied in a second color; circuit means coupled to said indicating means for producing a signal defining the portions of the original document to be copied in the first color and the second color; and means, responsive to the signal from said circuit means, for reproducing the original document with the portions of the copy corresponding to the indicated portions of the original document being formed in the first and second colors.
Claim 2
Independent Claim
125 words
An apparatus for forming at least a two color copy from a single color original document, including: a support member arranged to hold the original document thereon; means for adjustably indicating a portion of the original document to be copied in a first color and a portion of the original document to be copied in a second color; circuit means coupled to said indicating means for producing a signal defining the portions of the original document to be copied in the first color and the second color; and means, responsive to the signal from said circuit means, for reproducing the original document with the portions of the copy corresponding to the indicated portions of the original document being formed in the first and second colors.
Claim 3
Dependent Claim
16 words
An apparatus as recited in claim 1, wherein said reproducing means includes an electrophotographic printing machine.
Claim 4
Dependent Claim
173 words
An apparatus as recited in claim 2, wherein said electrophotographic printing machine includes: a photoconductive member; means for charging said photoconductive member to a substantially uniform potential; exposure means for projecting at least two light images of the original document onto said charged photoconductive member recording at least two electrostatic latent images thereon corresponding to the original document; means for erasing the portion of the first latent image to be reproduced in the second color and for erasing the portion of the second latent image to be reproduced in the first color; means for developing the unerased portion of the first latent image with toner particles of the first color and the unerased portion of the second latent image with toner particles of the second color; means for transferring the first color toner particles and the second color toner particles to a common copy sheet; and means for affixing substantially permanently the first and second color toner particles to the copy sheet forming a two color copy from a single color original document.
Claim 5
Dependent Claim
74 words
An apparatus as recited in claim 3, wherein said indicating means includes: a plurality of tab members mounted slidably on said support member closely adjacent to the side edge of the original document, a pair of said tab members being positioned to indicate the portion of the original document being reproduced in the first color; and a plurality of magnetic members, each of said magnetic members being secured to each of said tab members.
Claim 6
Dependent Claim
49 words
An apparatus as recited in claim 4, wherein said circuit means includes: a voltage source; and a switch coupling said voltage source to said erasing means, said switch being responsive to said magnetic member to connect electrically said voltage source to said erasing means, thereby energizing said erasing means.
Claim 7
Dependent Claim
27 words
An apparatus as recited in claim 5, wherein said erasing means includes a light source to illuminate and discharge the portion of the latent image being erased.
